CORE-RACK.

Application filed September 22, 1917. Serial No. 192,754.

To all whom 'it may concern,-

Be it known that l, HNRY M. LANE, a citizen of the United States, residing at Detroit, in the county of-Wayne and State of Michigan, have invente-d certain new and useful Improvements in Coro l`taclts, of which the following is a specification.

' This invention relates to core racks, upon Awhich a number of cores are placed and conveyed to e core oven for bakin, the racks remaining in the oven during the baking process and then being conveyed to a cooling room. The rack, comprising my present invention, is so constructed that a truck can be guided beneath it without displacing yor injuring the cores.

In making cores, it is the general practice to mold them and place them in an oven One Way of doing this is to provide stationary racks within the oven upon which the 4cores are placed. This is unsatisfactory as the placing of cores upon the racks requires considerable han- (lling, and also requires much time, reducing the output of the plant. A further ohjection is the delicate character of the unbaked or green cores which do not well with-y stand the handling incident tothis method of baking. A method more generally used however is the provision of wheeled racks,4

or racks permanently mounted upon trucks,

which are run into the core oven` the entire structure remaining in the oven throughout the baking process. lt has been found that certain parts of the truck (especially the Wheels and axles which support the entire weight of the rack and cores) are materially aected when subjected to the heat of the oven; and have to be 'frequently repaired or re laced.

n the present invention l have provided a separable rack and truck with special means to obviate jar or shock in assemblage, thereby avoiding displacement or injury ot the green cores. Y

In the accompanying drawings have shown several advantageous embodinu'ugits ot' my invention. ln this showing`l Figure 1 is an end elevation of one embodiment of the rack showinga truck support-ing the same;

Fig. 2 is a side elevation of the rack with the truck removed;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. l;

Fig. Il is a perspective view of one ofthe shelves;

Fig. 5 is a detail sectional view of a shelf;

Fig. 6 is an end elevation of another elnbodiment of the invention showing the truck in position;

7 is a side elevation of the construction shown in Fig. G, with the truck removed;

Fig. 8 is a transverse, horizontal sectional view on the line 6---6 of Fig. (3; and

Fig. 9 is a perspective view of the embodiment shown in Figs. G and 7.

In the construction of the rack shown (in Figs. 1 5) l provide four vertical posts A, and a plurality'of side bars yl connecting each pair of posts and forming the sides of the rack. These side bars are connected to the posts A by means of bolts or rivets 2. lin order to strengthen the parts and maintain a rigid connection I provide braces 3 consisting ot plates fastened to the posts A andto the side arms l. p

The transverse bars Il are connected to the posts A by means of bolts 5 and nuts 6; those bolts and nuts extending through openings in the side arms and through the open ings 7 in the posts. l provide a plurality oi openings 7 so that the bars 4 may be placed at any desired elevations and suitably spaced from each other, permitting the use of the rack with cores oi various sizes. As shown, the posts A and the hars 1 and 4 are constructed of angle irons and this is the best construction` although under sonic circumstances I may construct 'these parts of metal of other cross sections. The lower-most transverse bar 8 is best made channel or U-shaped as shown.

The channel shaped bai- 8 is connected to the vertical posts 1 with its arms extending horizomtalljvY and the angle bars 4 are also arranged with one arm extending iu the horizontal plane and the other arm in a vertical plane. thereby providing means ior fastening the bars 'to the posts A. Shelves B may rest on the horizontal flanged portion of the angle arms 4 and 8, allowing these shelves to be slid on and oil the rack. These shelves are best constructed of two longitudinal angle bars 9 which form the sides of the shelves, and a plurality of inverted channel bars mounted on the horizontal portions of the angle bars. The vertical portions of the bars 9 close the ends of the channel bars 10. Any suitable means may be employed for fastening bars 9' and 10 together. As shown, (see Fig. 5) I have employed rivets 11 for this purpose.

Two brace bars 12 (see Fig. 3) are' connected to the opposite ends of the lower portions of the channel bars 8, extending diagonally of Ithe rack, and being connected at their centers by rivets 13. This arrangement forms an additional means strengthening the framework of the rack and maintaining the parts in proper alinement.

I provide a pair of shoes 14 arranged on each side-of the rack and fastened at each end to the posts A, which serve to prevent the legs A. from digging holes in the Hoor; and also serve to distribute the weight of the rack over a greater area. As shown each shoe comprises an angle iron member the vertical arm of which is fastened to the post A. The horizontal arm extends beneath the post and serves as a shoe.

In the useof this rack it is necessary to guide a truck beneath the same without jarring or disturbing cores arranged upon the shelves. For this purpose I provide angle bars 15 connected by rivets 16 to the bar 8 and located between the posts A parallel to each other. The vertical portion 17 of the bars 15 lies adjacent the posts A, and forms a guide for a truck C which is adapted to be run ybeneath the rack. This truck is provided with a supplemental platform 18 having suitable means 19 for elevating the same whereby the rack may be raised from the door. After elevation it may then be conveyed to the core ovens, to a cooling room or to any other place, as the occasion may require.

In the embodiment shown in Figs. 6 to 9, the posts A and side bars 1 are similar to the construction shown in the other embodiment and are secured to each other in a similar manner. The transverse bars 4 are in y this instance replaced by similar bars Q0 having depressions 21 formed in their upper edges. These depressions form seats for the shelf forming members which in this instance comprise pipes or tubes 22. The tubes 2Q are secured in position by Cotter pins 23v or other fastening elements. The channel bars Q1, which are similar to the channel bars (8) in the other form of the invention, carry the diagonal brace rods 25 and 26 which are secured to the ends of the channel bars and riveted to each other at the center as indicated at 27 (see Fig. 8). l have also shown most shelf support 20. These diagonal racer rods are also riveted to each other yas :it-30. This upper brace construction may be emloyed with either construction' of the rack.

t the bottom of the vertical posts, are secured the shoesBl upon which the rack rests, and which serve to distribute the Weight over a greater area. Braces'32 are secured to the lower side bars andto the shoes. The guide bars 33, which are secured to the posts A are similar to the guide bars 15, and are provided with curved ends 34 which facilitate the proper positionin of the truck when the truck is run beneath t e rack.

The truck C, provided with the supplemental platform 18 capable Of-being lifted through the elevatin means 19, is employed in connection with tiis form of the invention.

5. A core rack comprising posts, side bars connected thereto, shelf supports mounted on the posts and arranged at right angles to the side bars, diagonally arranged brace bars connected to the rack, guide bars connected to the rack for guiding a truck beneath the frame and longitudinal bars connected to the lower terminals of the posts for forming a support for the rack.

6. In a machine of the character described, a rack comprising posts and side bars, end bars connecting the posts and forming shelf supports, guide bars carried by the rack, spaced from the bottom of said posts and arranged to guide a truck beneath the rack, and longitudinal bars connecting the lower terminals of the posts.
